Psilocybin Therapy for Chronic Low Back Pain

Registration Number
NCT05351541
Lead Sponsor
Joshua Woolley, MD, PhD
Brief Summary

This study evaluates whether psilocybin therapy helps patients cope with chronic low back pain more effectively. Patients may be recruited at Stanford and University of California San Francisco (UCSF), study procedures will occur at UCSF. Each participant will receive a dose of psilocybin with possibly one or more other drugs. Participants will undergo two preparation sessions, a dosing session, three integration sessions to discuss their psilocybin experience, and several follow up sessions.

Detailed Description

Chronic pain is associated with higher levels of pain-related distress, depression, emotional dysfunction, helplessness, hopelessness, and suicidality. Psilocybin is a psychoactive drug that may be well-suited to easing the psychological and emotional symptoms of distress associated with chronic pain. Previous studies testing psilocybin therapy have shown improvements on multiple behavioral and psychiatric outcomes, but it is unknown whether psilocybin therapy similarly enables patients to cope with chronic pain more effectively. The investigators will determine whether psilocybin therapy improves patients' ability to cope with chronic low back pain. If psilocybin therapy is an effective treatment in this population, its use could be incorporated into interventions for chronic low back pain and other psychological conditions.

Primary Outcome Measures
NameTimeMethod
Change in pain interferenceBaseline, 1-month after psilocybin session

The Brief Pain Inventory-Interference subscale (BPI) will be used to assess how pain interferes with a variety of daily activities (e.g., walking, lifting, mood, sleep, relationships). Seven items are rated on a scale from 0 (does not interfere) to 10 (completely interferes) for a total possible score ranging from 0 to 70. Higher scores represent greater interference from pain.

Secondary Outcome Measures
NameTimeMethod
Change in pain interferenceBaseline, 1-week, and 3-months

The Brief Pain Inventory-Interference subscale (BPI) will be used to assess how pain interferes with a variety of daily activities (e.g., walking, lifting, mood, sleep, relationships). Seven items are rated on a scale from 0 (does not interfere) to 10 (completely interferes) for a total possible score ranging from 0 to 70. Higher scores represent greater interference from pain.

Change in average pain intensityBaseline, 1-week, 1-month, and 3-months after psilocybin session

The Brief Pain Inventory with the Michigan Body Map will be used to assess pain location and worst, least, average, and present pain on a numerical rating scale from 0 (no pain) to 10 (pain as bad as you can imagine) over the past 24 hours, where higher scores represent greater pain intensity.

Change in depressive symptom severityBaseline, pre-dosing session, 5-days, 11-days, and 77-days after psilocybin session

The 7-item PROMIS-Depression self-report scale will be used as an additional indicator for changes in depression symptom severity. Items are endorsed on a 5-point scale ranging from 1 (Never) to 5 (Always). A higher total score represents greater depressive symptom severity.

Change in clinical depressive symptom severityBaseline, 1-week, 1-month, and 3-months after psilocybin session

The 17-item clinician administered Hamilton Rating Scale for Depression will be used to assess changes in the severity of depressive symptoms. Each item is scored by a clinician on a 3- or 5-point scale from 0 (Not present) to 4 (severe) and summed for a total score between 0 and 52. A higher total score represents greater depressive symptom severity.
